Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of functional textile materials, in particular to a windproof composite gradient wetting one-way wetting sports fabric and a preparation method thereof. BACKGROUND

[0002] Traditional one-way wetting fabrics generally achieve one-way wetting performance through the difference in hydrophilicity of internal and external fibers, and generally focus on moisture absorption and quick drying performance, but the windproof performance is insufficient, which is difficult to meet the sports needs in windy environment. Existing windproof fabrics are usually achieved through dense weaving or coating, but the air permeability and wetting efficiency are sacrificed. For example, the patent with publication number CN119615478A proposes a "one-way wetting and sweat-releasing fabric and a preparation method thereof", which utilizes the difference in hydrophilicity of cotton and polyester blended yarn and polyester yarn, and realizes one-way wetting effect by combining sandwich weaving method, but the one-way wetting effect of the fabric made by this method is poor, and the fabric does not have windproof property, which is not suitable for sports scenes in windy environment. For example, the patent with publication number CN119571624A proposes a "windproof and breathable composite fabric and application thereof", which adopts polyurethane padding, which enhances the windproof property, but leads to stiff fabric and decreased wetting performance, and poor washability, which cannot meet the needs of high-intensity outdoor sports. In view of this, the present application provides a windproof composite gradient wetting one-way wetting sports fabric and a preparation method thereof. SUMMARY

[0003] The technical problem to be solved by the present application is to provide a windproof composite gradient wetting one-way wetting sports fabric and a preparation method thereof. The purpose is to realize the synergistic optimization of efficient one-way wetting and windproof performance through the multiple composite design of the hydrophobic layer, the wetting layer and the windproof fabric layer woven by spandex covered with cashmere cotton.

[0004] The technical solution of the present application to solve the above technical problems is as follows: In a first aspect, the windproof composite gradient wetting one-way wetting sports fabric comprises a one-way wetting fabric layer and a windproof fabric layer; the one-way wetting fabric layer comprises a hydrophobic layer and a wetting layer; the windproof fabric layer is adhered to the wetting layer. The windproof fabric layer is woven by spandex covered with cashmere cotton.

[0005] The present application has the following advantages: (1) The windproof composite gradient wetting one-way wetting sports fabric of the present application adopts the composite gradient wetting principle, realizes the synergistic optimization of efficient one-way wetting and windproof performance through the multiple composite design of the hydrophobic layer, the wetting layer and the windproof fabric layer woven by spandex covered with cashmere cotton, and is suitable for sports scenes such as cycling and mountaineering that require windproof and quick drying. (2) The windproof type composite gradient wetting one-way wet conductive sportswear fabric of the application has high wet conductive and windproof synergy: one-way transmission index >=580 (GB / T 21655.2), moisture permeability >=18500 g / m²·24h (GB / T 12704), water drop diffusion time on the hydrophobic surface <5s, windproof property 3~5 cm³ / cm² / s; 3 / cm 2 / s; (3) The windproof type composite gradient wetting one-way wet conductive sportswear fabric of the application has light weight, durability and comfort.

[0006] On the basis of the above technical scheme, the application can also be improved as follows.

[0007] Further, the adhesion surface of the windproof fabric layer adhesively connected to the wet conductive layer has a hair height of <=3 mm and a hair density of 1500-2000 roots / cm².

[0008] The beneficial effect of the above further scheme is that by making the adhesion surface of the windproof fabric layer have a hair height of <=3 mm and a hair density of 1500-2000 roots / cm², the specific surface area is increased to achieve higher moisture absorption performance, and the adhesion strength (peeling strength >=8 N / cm, GB / T 2791) can be enhanced; through the special design and finishing of the windproof fabric layer, the windproof fabric layer has high wet conductive and moisture absorption performance, which makes up for the poor single conductive performance of the cotton wool organization, and finally realizes the synergistic optimization of high-efficiency one-way wet conductive and windproof performance.

[0009] Further, the warp yarn of the windproof fabric layer adopts 50S silk cotton covered spandex 20D (polyamide 70% / cotton 30%, polyamide is in the form of "Y" cross section), and the warp density is 110-120 roots / inch. The weft yarn of the windproof fabric layer adopts 32S silk cotton covered spandex 40D (polyamide 50% / cotton 50%), and the weft density is 90-100 roots / inch. The windproof fabric layer blocks airflow penetration through high-density plain weave structure (windproof property <=5 cm³ / cm² / s, ASTM D737).

[0010] Further, the windproof fabric layer is adhesively connected to the wet conductive layer through a polyurethane glue dot array, the glue amount is 3-8 g / m², and the glue dot density is <=15 pieces / cm².

[0011] The beneficial effect of the above further scheme is that the windproof fabric layer and the wet conductive layer are adhesively connected through a polyurethane glue dot array, the glue amount is 3-8 g / m², and the glue dot density is <=15 pieces / cm², and the air permeation channel is reserved.

[0012] Further, the one-way wet conductive fabric layer uses polypropylene filament as the bottom yarn and polyester (PET) filament as the surface yarn. The weight proportion of the polypropylene filament in the one-way moisture-conducting fabric layer is 28%-32%.

[0013] The one-way moisture-conducting fabric layer is a hydrophobic layer, and the moisture-conducting layer is a cotton hair weave.

[0014] The further scheme has the beneficial effects that the skin-cooling value Qmax of the polypropylene hydrophobic layer is greater than or equal to 0.20 W / cm², the anti-pilling level is 4-5 (GB / T 4802.2), and the abrasion resistance is greater than 20,000 revolutions.

[0015] Further, the one-way moisture-conducting fabric layer uses DTY 75D / 36f polypropylene filaments as bottom yarns and Y-shaped cross-section DTY 75D / 144f polyester filaments as surface yarns.

[0016] Further, the one-way moisture-conducting fabric layer has a grammage of 170 g / m²-180 g / m².

[0017] The one-way moisture-conducting fabric layer uses a cotton hair weave, which has a lower requirement for weaving equipment and a high efficiency, compared to the fine weave structure of a traditional one-way moisture-conducting fabric.

[0018] In a second aspect, a preparation method of the windproof composite gradient wetting one-way moisture-conducting sports fabric includes the following steps: (1) weaving the one-way moisture-conducting fabric layer; (2) weaving the windproof fabric layer: using silk cotton to cover spandex for knitting to obtain the windproof fabric layer; (3) compounding: bonding the windproof fabric layer and the one-way moisture-conducting fabric layer to obtain the windproof composite gradient wetting one-way moisture-conducting sports fabric.

[0019] Further, the step (1) of weaving the one-way moisture-conducting fabric layer includes the following steps: using a 32G double-face machine to weave, using polypropylene filaments as bottom yarns and polyester filaments as surface yarns.

[0020] Further, before bonding the windproof fabric layer and the one-way moisture-conducting fabric layer, the bonding surface of the windproof fabric layer is polished using a silicon carbide sanding roller. BRIEF DESCRIPTION OF DRAWINGS

[0023] The principles and features of the present application are described below, and the examples are only used to explain the present application, and are not used to limit the scope of the present application. If the specific technology or condition is not specified in the examples, it is performed according to the technology or condition described in the literature in the art, or according to the product manual. If the reagent or instrument is not specified by the manufacturer, it is a conventional product that can be purchased through a regular channel.

[0024] The traditional one-way moisture management fabric focuses on moisture absorption and quick drying performance, but the windproof performance is insufficient, which is difficult to meet the sports needs in outdoor windy scenes, and is limited by the gradient wetting structure design, high-performance fibers and precise processing technology. There are problems of difficult design and processing, and the single guide fabric is mostly knitted structure, and at present there is no systematic solution for the coordination and optimization of the moisture management and windproof performance according to the knitted structure. The existing windproof fabric usually adopts dense weaving or coating process, but it is not easy to guide moisture and sweat, and it is more likely to produce a hot feeling. The technical solution to solve the above technical problems is as follows: The embodiment provides a windproof composite gradient wetting one-way moisture management sports fabric 1 Figure 1 ), which comprises a one-way moisture management fabric layer and a windproof fabric layer 4; the one-way moisture management fabric layer comprises a hydrophobic layer 2 and a moisture management layer 3; the windproof fabric layer 4 is adhered to the moisture management layer 3; The windproof fabric layer 4 is knitted by wrapping spandex with cashmere.

[0025] In the preferred embodiment, the adhesion surface of the windproof fabric layer 4 adhered to the moisture management layer 3 has a hair height of ≤3 mm and a hair density of 1500-2000 roots / cm², such as 1500 roots / cm², 1800 roots / cm², 2000 roots / cm², and the like.

[0026] In the preferred embodiment, the warp yarn of the windproof fabric layer 4 is 50S cashmere wrapped with spandex 20D (polyamide 70% / cotton 30%, polyamide is "Y" shaped cross section), and the warp density is 110-120 roots / inch. The weft yarn of the windproof fabric layer 4 is 32S cashmere wrapped with spandex 40D (polyamide 50% / cotton 50%), and the weft density is 90-100 roots / inch. The windproof fabric layer 4 blocks airflow penetration through a high-density plain structure (windproof property ≤5 cm³ / cm² / s, ASTM D737).

[0027] In the preferred embodiment, the windproof fabric layer 4 is adhered to the moisture management layer 3 through a polyurethane glue dot array, the glue amount is 3-8 g / m², and the glue dot density is ≤15 pieces / cm².

[0028] Further, the unidirectional moisture-conducting fabric layer uses polypropylene filament as the ground yarn and polyester (PET) filament as the surface yarn. The weight proportion of the polypropylene filament in the unidirectional moisture-conducting fabric layer is 28%-32%, for example, 28%, 29%, 30%, 32%, and the like.

[0029] The unidirectional moisture-conducting fabric layer is a cotton hair weave, and the hydrophobic layer 2 and the moisture-conducting layer 3 are integrally woven.

[0030] Preferably, in the embodiment, the unidirectional moisture-conducting fabric layer uses DTY 75D / 36f polypropylene filament as the ground yarn and Y-shaped cross-section DTY 75D / 144f polyester filament as the surface yarn.

[0031] Preferably, in the embodiment, the unidirectional moisture-conducting fabric layer has a grammage of 170 g / m²-180 g / m², for example, 170 g / m², 150 g / m², 180 g / m², and the like.

[0032] The unidirectional moisture-conducting fabric layer uses cotton hair weave, which has a lower requirement for weaving equipment and higher efficiency compared to the fine weave structure of traditional single-conducting fabric, although the single-conducting effect is slightly worse.

[0033] In summary, the windproof type composite gradient moisture-conducting unidirectional moisture-conducting sports fabric 1 provided in the embodiment has the innovative point of the multi-layer composite structure. On the basis of the traditional single-conducting fabric hydrophobic layer 2 and the moisture-conducting layer 3, the windproof fabric layer 4 is innovatively added through the composite process. The windproof fabric layer 4 realizes excellent moisture absorption through special structural design and finishing, so that the windproof fabric layer 4 can quickly absorb the moisture of the moisture-conducting layer 3 and realize high-speed evaporation.

[0034] For example, the hydrophobic layer 2 uses DTY 75D / 36f polypropylene filament, the moisture-conducting layer 3 uses Y-shaped cross-section DTY 75D / 144f PET filament, the cotton hair weave has a grammage of 170-180 g / m², and the polypropylene proportion is 28%-32%. The loose structure reduces the retention of skin water, and compared to the fine weave structure of traditional single-conducting fabric, the cotton hair weave has a lower requirement for weaving equipment and higher efficiency, although the single-conducting effect is slightly worse.

[0035] For another example, the warp yarn of the windproof fabric layer 4 uses 50S brocade covered with spandex 20D (70% brocade / 30% cotton, the brocade has a Y-shaped cross-section), the warp density is 110-120 ends / inch, the weft yarn uses 32S brocade covered with spandex 40D (50% brocade / 50% cotton), and the weft density is 90-100 ends / inch. The high-density plain weave structure blocks airflow penetration (windproofness ≤5 cm³ / cm² / s, ASTM D737).

[0036] Wherein the windproof fabric layer 4 adheres to the mechanical polishing surface, the hair height is less than or equal to 3mm, and the hair density is 1500-2000 roots / cm² Figure 2 A and B), improve the specific surface area to achieve higher moisture absorption performance, and can enhance the adhesion strength (peeling strength ≥8N / cm, GB / T 2791). And through the special design and finishing of the windproof fabric layer 4, the windproof fabric layer 4 has high moisture conductivity and high moisture absorption performance, which makes up for the poor single conductivity of cotton wool organization, and finally realizes the synergistic optimization of efficient one-way moisture conductivity and windproof performance.

[0037] Glue point array bonding: the windproof fabric layer 4 and the moisture conductivity layer 3 are bonded by polyurethane glue point array, the glue amount is 3-8 g / m², the glue point density is less than or equal to 15 / cm², and the air permeation channel is reserved.

[0039] Preferably, in step (1), weaving the one-way moisture conductivity fabric layer comprises the following steps: using a 32G double-face machine for weaving, using polypropylene filament as the ground yarn and polyester filament as the surface yarn.

[0040] Preferably, before bonding the windproof fabric layer 4 and the one-way moisture conductivity fabric layer, the bonding surface of the windproof fabric layer 4 is polished by a silicon carbide milling roller.
